I am left handed and enby.
Though the correlation intersection is between enby (or peripheral to gender norms) and ASD, which is a broad intersection. It also informs my penchant for over-explaining things.
I'm not mansplaining, it's that the connectedness excites me like dinosaurs excite a toddler!
ETA Re: Anbidexterity, when I was in kindergarten I could, for a very short while, do letters with either hand and it was so cool. Then, in a playground accident, I broke my right forearm, so I learned to write while my right hand was in a cast. But yeah, I played piano (out of practice, now), and while I do mouse stuff with my left hand, I still joystick with my right hand due to early gaming on someone else's computer.
That said, for fine work or throwing, I do that with my left hand.
PSS: That all said, computer input devices come in three flavors: Right handed, ambidextrous and rare, often not great left handed devices I don't like. Usually I do ambidextrous options.
